Description

Pressure Strip is a butyl rubber tape used as an intensifier in corners where pressure is difficult to apply with only a vacuum bag. Pressure Strip is easily applied uncured on the prepreg layup and moulds to part shape during the cure cycle. Pressure Strip works from 120°C (250°F) up to 230°C (450°F) in autoclave or oven.

Benefits

• Eliminate resin rich corners on parts and reduce rework of parts and scrap.
• Simplify difficult bagging jobs with silicone free Pressure Strip (reducing contamination risk).
• An inexpensive alternative to re-tooling.

Application

• Apply one or more rolled pieces of Pressure Strip in the corner radius on top of the release film layer.
• Apply one or more pieces of Pressure Strip on top of the rolled piece to allow the product to form a
fillet during cure.
• Apply an additional layer of release film over the Pressure Strip layup.
• Complete vacuum bagging operation.
• A fillet will form during cure to prevent ply wrinkling and excessive resin buildup in the corner radius.

Notes

• The maximum use temperature is dependent upon the duration at maximum temperature and is process
specific, Airtech recommends testing prior to use.
• Watch a video of Pressure Strip in the "Media Center" on our website.
